A couple of artists have made a career of copying some of Brit Art’s most famous works… in Lego. “After experimenting with a Lego take on Damien Hirst’s formaldehyde shark, the pair have now graduated to their own mini-exhibition of modern art at the Walker gallery in Liverpool. Among the interpretations on display are Tracey Emin’s knicker-strewn bed, Salvador Dalí’s surreal lobster phone, and a rendering of the Turner Prize-winning transvestite potter, Grayson Perry, in one of his trademark doll outfits.
